Video: Overhauling the limited slip differential
Hi,
the video gives you step-by-step instructions on how to overhaul the limited-slip differential on a Porsche 944 Turbo. The gearbox was noticeable due to noise when cornering tightly. The cause is found in a broken friction washer. During the repair, the complete differential is checked and worked up. This is done using the tapered roller bearings of the differential and the plates of the limited slip system are exchanged. The video shows all the work in detail and explains the calibration procedure:
The video has a German soundtrack, but English subtitles are available on YouTube.
Enjoy it,
Jürgen

Ausgezeichnet!!! Vielen Dank.
Meine Transaxle ist derzeit zerlegt und wartet auf die Installation des neuen Diffs. ich muss aber andere shims verwenden... um mir die Einstellarbeit zu erleichtern habe ich die äußeren Lagerschalen der Diff-Lager abgeschliffen, dass diese mit Spielpassung ins Gehäuse gehen und ich den Spalt im verbauten Zustand messen kann. Das sollte mir einige Runden erparen.

In before the factory tool police....
Whatever the methodology, as long as you are confident in your work, the end result speaks for itself.
Dude's like this gather jobs built on reputation, he would have no jobs to make demo videos without success.
I worked with a guy who was a GM certified master tech in all mechanical groups.
It'd take him 1/2 a day to replace a pinion bearing and set up a diff by the book with all factory tools.
Problem was, warranty time for the job paid 2.3 hours.
By the end of pay week, he was starving with 20/40 hours.
To the contrary, myself on dealer commission labor at the time, "wasted" 1/2 a day making a feasibility plan to replace a factory defect fibrous cam gear by lowering 1/2 of the subframe to gain clearance to remove cover.
Warranty pay included R&R of the complete engine to do the job per factory bulletin, 12.5 hours pay start/finish.
No techs wanted to touch these because the job ties up a lift until finished and they couldn't come out under or equal the 12.5.
I was able to complete the job in less than 4 hours.
By the time I finished the 3rd or 4th one, every engine tech in the dealer was doing it my way.
There's a moral in there somewhere....
